To all whom it :niay concern v lie-it known that I, l'ixY FRANK(lIlAtKIN,

a 'eitizen of the United State.s and. a resident of (oney Island, in thefeoniity of' Kings and Stateof New York, have invented eertain new anduseful Iiiipmrenien'ts in l\'laehine's for Making Paper Dishes, e ofwhich. the following is. a1speeifiuitioi'ir My invention relates tomachines in which blanksflof-paperor other suitable fibrous or textilematerial. are rendered dish-shaped or more or less conea'red to formplates and other reeeptacles,'tlie blanks being heate l or baked duringcompression between male and feinaledies of suitable eonfigura tion to.setjthe shape desired; render the imparted.shape permanent for.

In order to all practical p n-poses for \\'l\lt2ll.-S ll(;li a'rtieiesare'des gned it,- is neeessary that the baking" period i, c.;ithet'iir'iednrii'i'g whieh' the blanks are held between the he:'itel-dies,='

This necessarily lii iited-thc speed and outputof the.inacliiiie,'besides rendering its operation uncertain, sincev the pviiigto expansion of" dies front overretnactile springs'eould not be relied qion to HlViU'lably separate the male. and '1e.inale V dies heatingduring long-run or the sticking of forced away from tlie.,. :tationaryftaiialerdie head, or the machine stopped until the dies eooled.ollZYiii'the blanks ceased to 'bind, the loss in time and. proi'liietthii involved NEW YORK, ASSIGNOB, TO ALFRED BLEYEB t AcHiNE- OR'M'AKINGPAPER msmas, a;

Each female die 0, is provided with an ejector a, for. insuring' thedischarge of the dished blanks at the proper time. Each ejector e, ispreferably arranged centrally or axially with relation to its respectivedie a, being mounted in and through a cross web I), of thedie head B, B,as shown more particularly in t, and being formed with a collar 1:,which contacts with the outer face 1 of the die head to limitthe inward,thrust of the ejectorg-a spring a", being interposed between saidcollar 0', and a cross bar a", through which the outer end of the ejec;

tor e, passes, so thatthe spring e", t ends eonstantly to thrusttheeject'or inward. The

cross bar a, is supported upon the stationary die head B, B, by anysuitable means as by the screw studs 0*. shown. \l 'hen the blank isforced into the female (lies 0, by

the maledies d, it is obvious that the ejectorsz:,' will be forced backagainst the re sistanee of' thesprings a", which latter will force theejectors c, c, to strip said female dies 0, as soon as the male dies areretracted therefrom.
